2 Claims. (Cl. 229-86) The present invention relates to new and useplates 9 is provided with a tongue 10 which is ful improvements in envelopes, and more paradapted to be bent upon itself as at 11 after it ticularly it pertains to an opening device therehas been passed through its respective loop 8 of for. the ripping element 7. Means is provided for 5 It is one of the objects of the present invention securing these metallic plates 9 in position in the to provide a new and novel opening means for envelope, ,and this means preferably comprises I envelopes. integral tongues or the like 13 which are bent A feature of the invention resides in a novel upon themselves as at 14 in Figure after'they form of ripping element adapted to tear through have been passed through the material forming a folded edge of an envelope to provide access to one wall of the envelope thus securing the metal- 65 the interior thereof after the same has been lic plate 9 in position. 1 sealed. By reference to Figure 4 it will be noted that A further feature of the invention resides in a one of these metallic plates 9 is/positioned in a novel form of means for anchoring the ends of corner between the corner and the line of per- 15 a ripping element and thereby providing means foration heretoforementioned in such a manner 7 for securing the ripping element within one of that when the envelope is torn along the line of the folded edges of an envelope. perforations, the member 9 will be removed with Other features of the invention will be apparrelation to the main body of the envelope and ent as the nature of the invention is better underthe ripping element may be employed to sever g stood, and with this object in view, reference is the folded edge of the envelope as illustrated in 75,

had to the accompanying drawing, wherein: Figure 3.

Figure l is a view in elevation of an envelope Thus it will be apparent that one of the arrconstructed in accordance with the present inchoring means becomes the operating member vention, the envelope being shown-sealed, for the ripping element when the said member Figure 2 is a similar view showing a portion 9 is separated from the main body oi the engo of the envelope removed, velope by tearing the same along the line of Figure 3 is a similar View showing the ripping perforation. element and its position during the envelope It will be apparent that the present invention opening operation, provides an effective and novel means for ango Figure 4 is a longitudinal sectional view on choring a ripping element within the fold of an as an enlarged scale illustrating the position of the envelope in such a manner that the ripping eleripping element with respect to the envelope and ment may be employed to open the envelope as the means for securing the ripping element withdesired.

in t e e v p and While the invention has been herein illustrat- Figure 5 is an enlarged detail sectional view ed in a preferred form, it is to be understood that go taken on the line 5-5 of Figure 4. the invention is not to be limited to the specific Referring more specifically to the drawing, the details of construction herein illustrated, and reference character 5 designates the envelope, that it may be practiced in other forms without and in carrying out the invention, the envelope departing from the spirit of the invention.

40 is provided with a line of perforations designated Having thus described the invention, what legs 6 which preferably extend diagonally across one claimed as new, and what it is desired to secure corner of the envelope as illustrated herein. by Letters-Patent of the United States, is:

A pp element preferably in the form of 1. In combination with an envelope, an open= a length of relatively small fine wire is provided, ing device for the same, including a cord with a and as Shown in Figure 4 this pp element is loop at each end; two plates of single sheet maadap d t nd a e n d f th nv lop terial placed in two corners of the envelope at in parallelism therewith, and be positioned in the th t d of th edge of the envelope to be fold thereof as best illustrated in Figure 4. This opened, each plate having a triangular shape, an ripp e t has loopends 8 t e pu pose of integral strip forming an extension oi one side which will be hereinafter described. of the plate in parallelism with the edge of the Means is provided for anchoring the ripping envelope to be opened, said strip being bent over element '7 in position in the envelope, and in the itself and engaging the loop at the respective present embodiment of the invention, this anchorend of the cord; two prongs struck out from the ing means comprises two metallicrplates 9 made edges of the triangular plate adjacent to and in 55 of relatively thin metal. Each of these metallic parallelism with the axis of said strip, adapted to penetrate through the material of the envelope and secure said triangular plate thereto by being bent thereover, and a row of perforations across one corner of the envelope, one side of each triangular plate being placed diagonally across the respective corner of the envelope and said row of perforations following said diagonal edge of the respective plate but being inside thereof for a free removal of the plate.

2. In an envelope opening device having a ripping cord with a loop at its end, an anchoring plate being a triangular shaped piece of sheet material secured in a corner of said envelope, the two sides thereof being in parallelism with
